Wire-O binding is known by many names: double-loop, double-o, double-wire, Twin Ring Wire and also twin-loop binding. This method uses a continuous hinge of double wire loops to hold book covers and pages together. Graphic designers prefer this method, because it offers a stylish metal finish in a variety of colors. This traditional method of wire binding secures pages, so that they cannot be modified without unbinding the book. Books bound using the Wire-O method tend to lie flat, and sheets can turn 360°, which is ideal for calendars or notebooks. Pair with our Twin Ring Wire Binding Machine that range from low volume to full production floor models. Browse our selection of Wire-O binding supplies today to find 11" wire options, spools, hangers, and much more.

For businesses who need to create professional-quality books, Wire-O binding is the best solution. This kind of binding offers a clean and high-class appeal that is unmatched by any other traditional binding method. Our selection of Wire-O binding supplies includes twin-loop wire spines in an array of pitch options and color varieties. 3:1 pitch Wire-O comes in sizes from ¼ inches up to 9/16 inches, which means it can be used for books from 2 to 120 sheets in size. 2:1 pitch Wire-O is typically available in the larger sizes from 5/8 inches up to 1 1/2 inches, perfect for books from 135 to 280 sheets in size, but we also offer unique 2:1 wires in the full range of sizes, offering more versatility. All sizes are available in bulk, 100 wires per box. Double-loop binding can be easily cut using any standard pair of wire cutters from a hardware store, however, if you need larger quantities of a specific non-standard length, then it may be more cost-effective and convenient to have us custom-cut them for you with our specialized equipment.

Our selection of Wire-O binding supplies includes wire calendar hangers and manual thumb cut punch machines to make crafting easy for everyone. With a pack of 100 wire hangers, you can DIY your own wall-hanging calendars in just a few simple steps, and spend as little as just a couple dollars per calendar.
